XVILLIAM H. THURMOND, OF FORSYTH, GEORGIA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 289,729, dated December 4, 1883 Application filed September 25,1883. (No model.)

.To all whom it may concern/.-

Be it known that I, W'ILLIAM H. THUR- MOND, a citizen of the United States, residing at Forsyth, in the county of Monroe and State of Georgia, have invented certain new and useful Improvements in Gar-Couplings; and I do hereby'declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, in which Figure l is a top view of my improved railroad-car coupler. Fig. 2 is a section taken longitudinally through the same in the vertical plane indicated by the dotted line 00 00 on Fig. 1. Fig. 3 is a section taken horizontally through the coupler in the plane indicated by dotted line y y.

My invention relates to the Well-known hooked couplers for cars or passenger-coaches; and it consists, essentially, in the devices which I shall hereinafter describe, reference being had to theannexed drawings.

A designates a draw-bar, which is recessed longitudinally and vertically, and provided in its longitudinal recess with backwardly-inclined surfaces a a, the forward one of which forms a shoulder, a". This shoulder leads down to an opening or recess, 12, adapted to receive a vertical coupling-pin when it is necessary to use the well-known coupling-link. Anterior to this recess 7) is formed on the draw-bar a curved portion, 0, a web, 0, an ear, O and a rectangular portion, O. This gives a general description of that part of the.

draw-bar which I designate the part A, and which maybe formed entire. Upon this drawbar section I apply a capping-section, which I shall now, for the purpose of description, denominate A This part A is adapted to be fitted squarely on the part A, and in practice it is a part thereof. The bottom of this part or capping-section A is flat, and it is so constructed with its wings and ears I) c d and its vertical passage that it accurately fits upon the lower section of the coupler. This upper section of the coupler, which, let it be understood, conforms in every particular to the lower section, is constructed with ears 9 g,

which are perforated transversely to receive a rock.-shaft, G. Between the ears of the upper section of the draw-bar, and fast on the rock-shaft G, is a bifurcated arm, G, which receives between its prongs a pin, h, which is applied rigidly to a longitudinally-movable thrust-bar, J, fitted into the recess in the base portions of the draw-bar. On one end of the oscillating bar or rock-shaft G is an arm, G Through the aperture 6 of the upper section of the draw-bar head is a latch, e, the object of the lower beveled nose of which will be hereinafter explained. The upper section of the draw-bar is shouldered at s, and it is rigidly secured to the lower section by bolts or other suitablemeans.

The ear I) has pivoted to it a coupling-hook, H, which is constructed with a tail, H, beveled at H and also with shoulders, which are segments of circles concentric to the axis of movement of thesaid jaw. The tail of this locking jaw or hook H is always in such relation to the thrust-bar J that when the crankarm above described is moved forward an uncoupling can be effected. It will be observed wit, a longitudinal movement and a vertical movement. It will also be observed that there is a beveled surface, H on the tail of the hooked coupling device H. Furthermore, it will be observed that I effect a safe self-coupler by very simple means. g The draw-bar is preferably cast entire. The j aw or brace is so applied to the draw-bar that it can be adjusted or set for coupling or uncoupling, the bumping being on the outside of the draw-head, so that the working parts are practically protected.

There is one very essential feature of my invention, which consists in the thrust-bar actuated as described, and so arranged that it 0 acts to lock the pivoted coupling-jaw. By retracting the thrust-bar the coupling-jaw is released, and an uncoupling can be effected.

It will be observed that when the thrustcoupling-jaw, and that when said bar is retracted it will allow an uncoupling.

I am aware of Patents Nos. 156,024, of

that the thrust-bar J has two movements-to 75 bar is projected it is practically a lock for the 9 5. I

1874, and 188,405, of 1873, and the construcand crank-lever G all arranged and operattions therein set forth are not sought to be ing as set forth. 10 covered in this application. In testimony whereof I aflix my signature in Having described my invention, I claimpresence of two witnesses. 5 In combination with the pivoted coupling- WILLIAM H. TI-IUBMOND.
